' TO-ALL -WHOM ITMAY CONCERN Be it known that I', Bonson 'Evsnn'rn of Philadelphia, Penne lvani'a, 'havein vented an improved Joint for Tinned-Iron Vessels; und I do hereby declare the following to be a'fnll, clear, and' exact de'scriptionof the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists in the peculiar construction, described hereafter, of the joints of tinned iron vessels,

such, for instance, as the square or oblong vessels nsedfor containing or transporting petroleum, which require joints of a more thaln ordinary tight and rigid character. v Y l A In order to enable others skilled in the art to practise my invention,I will non'. proceed to describe the mannenof carryingit into effect. 0n reference to the accompanying drawin'g, .vi'hch formes.4 part of this specification- Y 'Figure 1 represents tw'o pieces of ,tnned' plate prepared for making the joint.

Figaro 2, the two pieces fitted together; and i i Fignret shows the two pieces soldered, and the joint formed. A represents aportion of the top of a .vessel of "tinne'dl plate-nnd B a-porton'of the side of the same -vessel In order to "secure the top plate' Ato the. side plates B, I form on the edges-of, the plate AV a flange, a,

which is slightly inclined iuwards,'as shoiv'n in the drawing; and on the' sideplates B,I form a horizontal' angeJv, below whichI indent the plates so esto form a groove or channel, a. I then apply the plate A to the side plates vIB, inthe manner shown in'iig. 2, the ilange' a projecting partly-'across the channelaz, into vrhieh vIv bendthe said flange a, as seen in iig. 3. I then fill, or partly'iill, 'the channel with solder, as seen in g 3, thereby forming a perfectly tight and secure joint. f- A y In many tin vessels or cans,-and especially .such as are used for containing 'and' transporting' petroleum, it is of the greatest importance that the joints. at theseverl edges should 'not only *beperfectly tight, but should also be of such a strength as to withstand all reasonable shocks or jars to which they may be' subjected. Experi- Vments have been made with different joints, some of which `have', beienextensively rised, but, although more or lessV ciiic'ient, they are complex and expensive to make. It will-be seen thatthe above-described "joint is of the Y in ost simplecharacter; makingfthe flanges, forming the channehgrand applying l th'pv solder"being e'ected liyl the most simple appliances and. ready-manipulation; at the rsameltin'ie thinteriial flange b, overlapping flange a, and the solder, tend to make `the edges of the 'Y can' of niore than-` ordinary strg'alig'th. I have alluded tothe piece A as part of the upper plate of the can orvessel, and to B as part of the 'sidevplate, but it will Vbe readily i understood that the plate A may represent `one of the side'plate'sor the bottom plate'.

- I claim as my invention, and 'desire to secure by 'Letters Iiatentf-L .1 A

The 'gvithin-described joint for tinned plate vessels, that s to say, 1the ilange b and channel 2: ou the plate i B, and the ilnge a on the plate A, projecting partly across and into the said channel, and there soldered, all

as set'forth- In testimony whereofv I have signed my name to this specification inthe presenceof' two subscribing Witnesses.
